Application filed November 16, 1911. Scrial'No. 660,550.

The present invention relates to sole pressing machines, and more particularly to machines of this type which are employed for operating upon fiat soles prior to thelr 1ncorporation in boots and shoes.

The majority of soles have a size number or other designating character stamped upon the surface in order that they may be readily identified by the operator and the expense of manufacture of the shoe is lessened if this operation can be performed in conjunction with some other operation, as, for example, the pressing of the sole which takes place prior to the incorporatlon of the sole in the shoe.

One object of the present invention is to enable a suitable designating character to be imprinted upon the surface of the sole without necessitating an increased number of operations upon the sole or otherwise adding to the expense of manufacture of the shoe. I

l Vith this object in view, a feature of the invention consists in the combination of a pair of cooperating pressing forms for molding the sole, a marking device for imprinting a designating character upon the sole, and mechanism for actuating the marking device after the sole is positioned upon one of the forms.

A further object of the invention is to provide a marking device of an improved construction which is efficient in its operation and'which maybe readily and conveniently adjusted to stamp different marklngs upon the sole.

With this end in view, a further feature of the invention consists in the provision of a plurality of disks having designating characters formed upon the peripheries and mechanism conveniently accessible to the operator for securing a relative rotation of the disks to enable any desired combination of the characters to be obtained.

A still further feature of the invention comprises a" plurality of disks having designating characters formed on their peripheral surfaces, and mechanism conveniently accessible to the operator for adjusting the disks in unison to insure an even and uniform marking of the work.

Broadly considered these features of the invention are not limited to the employment of a marking device of the character de scribed with a sole pressing machine but contemplates the use, if so desired, of the im proved marking device, either alone or in conjunction with any other type of machine.

Still further features of the invention comprise certain novel features of construction, combinations and ar 'angements of parts hereinafter described and claimed, the advantages of which will be apparent to those skilled in the art from the following description.

In the accompanying drawings illustrating the preferred form of the invention; Figure 1 is a plan view of the improved marking device applied to a sole molding machine; Fig. 2 is a side elevation of the marking device shown in Fig. 1 and illustrating the device in an inoperative position; Fig. 3 is an end elevation upon an enlarged scale of the device shown in Fig. 1; Fig. 4 is a detail illustrating upon an enlarged scale the mechanism for adjusting the marking device to enable the proper character to be stamped upon the sole; Fig. 5 is a diagrammatic view illustrating the arrangement of the characters showing the manner in which any desired combination of characters may be obtained and Fig. 6

is a detail showing the heel portion of a flat sole with the proper size number marked thereon.

The illustrated embodiment of the invention is shown in connection with a sole molding machine of the type shown and described in the patent. toPreble No. 1,004.,075, September 26, 1911. This machine consists of a lower supporting form indicated at 1 and cooperating with a stationary sole pressing form 1*. The supporting form 1 is mounted upon a horizontal slide 2 which is reciprocated in a cross head 3 to move the form from a position of presentation to a position of clearance and vice versa. The form is moved from a position of clearance into a pressure producing position by power actuated. mechanism which is operatively connected to the cross head 3 to move the same in a vertical direction. The flat sole is vision of a sole marking 7 ment of the form positioned longitudinally of the form by a heel gage indicated at 4: and is clamped to the form by a gripping device 6 actuated by a roll 7 upon the movement of the form from a position of presentation into a position of clearance. This construction is fully described in the patent above referred to and as it forms no part of the present invention, has been only briefly described herein.

The present invention consists in the prodevice operating in conjunction with a sole molding machine which enables the proper designating character to be automaticallystamped upon the surface of the sole without necessitating an added operation or detracting from the etliciency of the molding operation. The markstamp the size ing device is arranged to number upon the sole prior to the molding operation and after the sole has been positioned properly upon the supporting form. In the simplest and most efiicient form of the invention which has yet been devised, the marking device is actuated bv the move from a position of presentation to a position of clearance, and

after imprinting the size number upon the heel of the sole, the marking device is retained in this position to clamp the sole to the supporting form during the pressing operation. An arm 10 is pivoted to the slide 2 at 11 and carries a suitable marking device indicated at 12 upon its outer free end.

The sole gripping device 6 consists of a narrow arm supported adjacent to the arm 10 and pivoted to the slide 2 at 13. The pivotal connection 13 is located in advance of the pivotal connection 11 so that as the slide 2 moves horizontally the roll 7 first passes over the pivotal connection-13, and actuates the gripping device to clamp the sole to the form. A still further movement of the slide in the same direction causes the roll to travel beyond the pivotal point 11, thus moving the marking device 12 into operative engagement with the surface of the sole. With this construction and arrangelnent the sole is clamped firmly in position during the operation of stamping by an independent clamping mechanism and is thereafter held by the marking device. It will be noted from an inspection of Fig. 2 that the upper face of the gripping device 6 is slightly lower thanthe corresponding face of the arm 10 so that after the roll 7 has moved the marking device into operative engagement with the sole it retains the marking device in this position to clamp the sole to the form. Thus the marking device serves the double function of imprinting a designating character upon the sole and of clamping the sole to the form simultaneously with the stamping operation.

In addition to automatically marking a designating character upon the sole, the marking device has provision for adjustment in order to enable the sole to be marked with any desired character within certain prescribed limits. This is accomplished by a simple and eflicient adjusting mechanism which extends forward to the front of the machine where it may be readily manipulated by the operator. In the illustrated embodiment of the invention, a pair of disks 15 and 16 are journaled in the free end of the arm 10 and the periphery of each disk is provided with a series of raised figures as shown clearly in Fig. 1. The disk 15 is secured upon a shaft 17 and the disk 16 is socured upon a second shaft 18 sleeved upon the shaft 17, and loosely journaled in a sleeve 20 extending laterally from the arm 10. The outer end of the shaft 17 carries apinion 21 which meshes with a rack 23 cut upon the under face of an operating rod 25. The rod 25 is slidingly mounted at its opposite ends in bearing members formed respectively in the sleeve 20 and in a bracket 28 secured to the machine frame. The rod 25 extends forward to the front of the machine and is provided at its outer end with a rack 30 which meshes with a toothed segment 31, loosely mounted upon a shaft 32 secured in the bracket 28. lVith this construction by manipulating the segment 31, the operator is enabled to slide the rod 25 longitudinally and rotate the disk 15 any desired amount. In order to adjust the marking disk 16, an operating rod is sleeved upon the rod 25 and is provided at its inner end with a laterally offset projection on the under face of which is cut a. rack The rack 34 meshes with a pinion 35 secured upon the shaft 18 and is retained in engagement with the pinion by a yoke shaped extension formed upon the sleeve 20 and surrounding the inner end of the rod 33. The outer end of the rod 33 is provided with a second ofiset projection upon the under face of which is cut a rack 36 which meshes with a toothed segment 37 journaled upon the shaft 32. In order to accurately adjust the marking disks from the front of the machine without making it necessary for the operator to observe the peripheries of the disks, an indicating member 38 is located between the toothed segments 31 and 37, and is provided with a peripheral face having two rows of designating characters corresponding to the designating characters upon the two marking disks.

The segments are provided respectively with spring pressed latch pins 40 and 41 which are arranged to engage with a series of recesses formed in opposite sides of the member 38. VV1th this construction and arrangement it is only necessary to adjust each segment until the latch pin engages with the recess opposite the proper member. It sometimes happens that on account of the substitution of different-sized forms, or for other reasons, the marking disks do not locate the size numbers parallel to the surface of the sole so that the size number is not printed evenly and uniformly. In order to obviate this difficulty, the indicating member 38 is provided with a worm gear at which meshes with a worm 4L3 journaled in the bracket 28 so that upon rotating the worm 43 the indicating member 38 together with the segments 31 and 37 is adjusted angularly about the shaft 32. Thus the indicating member and segments are normally locked in the position to which they are adjusted, which position may be varied, however, by rotating the worm 43. A handle 45 is secured to the outer end of the worm shaft and a clamping screw 16 normally locks the worm 13 and prevents accidental displacement of the indicating member and segments during the operation of the machine.

It is necessary for the successful operation of the machine to provide some means for automatically removing the heel gage either in whole or in part from beneath the marking device before the latter engages with the sole. To this end one wing of the heel gage is pivoted at 51 and is provided with an arm 52 engaging with an upstanding pin 53 which is moved in the same direction as the slide 2 and at a higher rate of speed during the movement of the slide from a position of presentation to a position of clearance. This movement is so timed that the pin 53 engages with the arm 52 and swings the wing 50 out of the path of the sleeve 20 before the latter reaches the limit of its downward movement. The pin 53 ex tends upwardly from a sleeve 5a slidingly mounted upon a shaft 55 which is secured to the slide 2 and a rack 56 is cut upon one side of the sleeve and meshes with a toothed segment 57 pivoted to the slide. In order to prevent an angular movement of the slide 5%, a guide rod 58 is secured to the slide above the shaft 55 and slides in a bearing member 59 which is mounted upon the frame and which serves to support the shaft A rack 60 is secured to the cross head 3 and meshes with a pinion 61 journaled upon the slide 2, and carrying a crank pin 62 which engages with a slot 63 formed in the segment 57. As the pinion 61 is rotated in the direction of the arrow by a movement of the slide from a position of presentation to a position of clearance, the toothed segment 57 is oscillated in the opposite direction by the crank pin 62 and in the same direction as the direction of movement of the slide. Thus the sleeve 54 upon an inward movement of the slide is moved in the same direction and at a higher rate of speed to cause the pin 53 to engage with the arm 52 and swing the wing 50 into an inoperative position. In order to return the wing 50 to its initial position and restore the form of the heel gage, a spring pressed pin 65 is slidingly mounted in a casing 66 and engages with a rib 67 formed upon the under side of the wing 50 and normally tends to move the wing back into its operative position.
